3. Story walkthrough
Full video walkthrough with commentary I made for easing the completion:
As soon as you have control of your character, press to dive down into the water. Pressing will accelerate you. The first thing you want to do is press while swimming towards the surface of the water to leap out and earn your first achievement:
Leap from the water.
Continue swimming towards the large hole in the wall, and as you approach a large fish will swim out towards you, prompting you to grab onto it with . While holding this button, you can ride it and guide it where you want to go. While riding the fish, press and you will flip with the fish, earning another miscellaneous achievement:
Perform a flip while riding a creature.
Let go of the fish and continue through the small cave to pass through a wall of seaweed. In front of you is a rock formation, pass around the right side of it and you will see in the distance some pink coral formed around a small crater. These are Hidden Pools, one type of collectible in the game (pictured below) that we must swim up to and press to interact with Hidden Pool (1/20).
Now follow the sandy path that the pool sits on back towards the entrance of the area past the rock formation. The sand path will split, follow the left path to find another Hidden Pool (2/20).
There will be a small cliff just past this pool with light radiating down. Swim to the sand pit down here with a small flashing light in the middle. Interact with the light to collect a small droid. Now turn to your right to see a gap between the seaweed and a cliff, swim down between these and you will see a Hidden Pool (3/20) a short distance away.
While above the pool, look up to the top of the stone walls ahead of you and you will see a statue of a shark. These are Meditation Statues (1/12) that need to be interacted with for an achievement. Go ahead and swim to it and press when prompted.
While sitting on the statue, press to go into View mode. Moving will change what fish the camera is focused on. Continue moving from fish to fish until you randomly see a fish get eaten. This will unlock an achievement, but if you aren't having any luck then there are multiple opportunities to unlock this achievement.
Witness predation while meditating.
Hop off of the statue and dive straight down and to the left, and inside the rock structure will be a Shell (1/19) to collect, the final kind of collectibles in the game.
Turn around and head out of the rocks (towards where the meditation statue is looking) and swim towards the beams of light where you will find another droid stuck in the sand. Retrieve it and turn around, and you will see a large hole in a wall along the seaweed wall to the left, and there will be beams of light behind it. Swim up there and you will see the 3rd droid for this area.
After saving the droid, return to where you found the second droid, and you will see a little doorway that is obstructed by red coral. You should be able to interact with this coral and one of the droids will open the way for you.
Continue forward and you will see a shark head through some seaweed. Follow it through, swim past some green eels and head through a large hole in the wall and hook an immediate left to find a Shell (2/19) around the corner.
Follow the linear path until you come to a large dark area. Head towards a glowing pool near the bottom and you will swim into it. When you spawn in the new area, the game will point you towards a tower that you need to swim towards. There is a ball of fluid that you need to interact with to trigger a cutscene.
When you gain control of your character, look above the door that just opened to find a Meditation Statue (2/12).
Hop off of the statue when you're ready and head through the door below. Pass through the cave until you are in an open area, where the shark will destroy one of your droids. When you can move again, dive straight down to the sea floor.
Between the first two pillars will be a Hidden Pool (4/20).
Swim forward around to the other side of the last pillar to find a Shell (3/19) in the open.
Now follow the pillar up to find a giant triangular gate. Head to the center of it and interact with it, and when it opens swim through to finish the chapter.
When you can move again, swim forward into the sea current. There are many sections like this in the game, and in each there will be schools of fish to swim through. When you touch them, they will flash white to confirm that you have been successful. Do this to 15 groups to get an achievement (there are more than enough to get this achievement, so don't worry about missing).
Burst 15 fish schools in the jetstream.
At the end of the sea current section, you will be spit out into a pink area. Look to your left and you will see a Hidden Pool (5/20) along the sand path.
There will be a Meditation Statue (3/12) next to the pool (to the right if you went straight from the entrance of this area to the pool)
From the statue, you will see a huge pillar on the other side of the area. Head to the top of it for a Shell (4/19).
There will also be a Hidden Pool (6/20) near the base of this pillar. After collecting the shell, be sure to swim down and interact with the pool as well.
Now turn around and head to the opposite side of the entrance to see a cave with two entrances. On top of this cave will be the last Hidden Pool (7/20) of the area.
Now swim into the cave directly below you and save the droid in the sand there. Afterwards, exit the cave and head under the rock formation with the hole in the center. There will be a reef door that the droid will be able to open up.
Read this before progressing! Past this door is another current section, but unlike all of the current sections in the game, this one has a shell you need to collect in it!
During the section, keep an eye out for a large stone archway you will be passing under:
When you pass through the arch, stick to the top left side of the current and you will see the Shell (5/19) on a small ledge (I also unlocked the Jetstream achievement here).
Continue through the current section until it spits you out into a dead area. There will be another glowing pool in the center towards the bottom, swim into this. In the hub area, swim towards the highlighted tower and interact with the liquid again to revitalize the previous zone.
When you gain control of your character, look to the left of the tower nearby and you will see a Meditation Statue (4/12) in the distance.
When you're done with collecting that, continue through the newly opened door and swim through the cave that follows. In the open area that you come to, swim under an enormous school of fish that you want to swim under to find another Meditation Statue (5/12).
Now jump off of that and dive straight down to the sea floor. On the way down, you will notice a Hidden Pool (8/20) at the base of the pillar.
Now swim around the pillar until you see a Shell (6/19) surrounded by 3 rocks and some pottery.
Now swim up to the top of the pillar and head towards the large triangular gate. Interact with the center to enter and end the chapter.
In the next area, swim the cave until you come to a huge open area. Head to the left towards a large thin statue where a droid will be stuck in the top waiting to be rescued.
A little past the droid will be the next Hidden Pool (9/20) on a cliff at about the same level as the droid.
Now swim up to the top of the cliff nearby (you should be facing it if you went straight from the droid to the pool) and you will find a Meditation Statue (6/12).
Directly behind the statue will be a well, swim to the bottom of this well to get the next Shell (7/19).
Swim to the top of the well and swim between the Meditation Statue and the pillar to it's left and swim over the statues (similar to the ones you collected the droid from), and if you keep swimming in this direction you will see a cliff with a Hidden Pool (10/20).
Now swim straight off the ledge and dive straight down to the deepest point of the area. While on the floor here, you will see another Hidden Pool (11/20) in the sand path.
Now follow the sand path (in either direction, it loops around, but left in my screenshot is the fastest way) and you will find a small stone structure with a drone trapped in the top.
After collecting it, swim up while looking at the nearby wall until you see a bright doorway with a chain leading through it. If you get lost, find the chain leading from the right side of the exit door and follow it.
After opening this door, follow the chain to a crank. Interact with it and then exit the cave after the cutscene. Head across to the opposite side of the area to a cave for the second crank.
After the second cutscene, head through the opened door. Swim towards the floor of the hallway and shortly after the sand path begins you will see a Hidden Pool (12/20).
Continue and you will see the shark swim through the room. Head to the right through the seaweed and you will find a Shell (8/19)
Follow the linear path and you will eventually come out to another dead area. Swim to the pool and complete the hub area to revitalize the region.
When you regain control, swim to the right around the coral pillar and you will see a Meditation Statue (7/12) up high on a ledge.
Now if you look in the direction you're facing while sitting on the statue, then turn to your right you will see several arches. Swim into these arches and there will be a Shell (9/19) hidden back behind here. If you get lost, find the doorway to progress and swim directly up the wall above it.
Now swim directly down and through the doorway.
In this new area, there will be yellow-trimmed fountains to interact with. Doing so will cause liquid to flow through the doors that will open them. After the second fountain, swim down the large hallway and as you come to the 3rd fountain there will be a Meditation Statue (8/12) in the back right corner of the room. You can collect this before or after you activate the fountain, it doesn't matter.
Pass through this last doorway and swim down the linear path until you come to another triangular gate to end the chapter.
Proceed down the path until you get to some whales. This will trigger what's essentially a cutscene where you swim to the sea floor with them. When you get to the bottom, you may notice floating triangular structures. These are mines that will stun you if you get too close, so try to avoid them.
Swim in their direction and soon you will see a Hidden Pool (13/20) in the open.
Swim up the wall to the left and you will find a Meditation Statue (9/12) nearby (you can see the silhouette of it on the left in the previous screenshot).
Now scan the area until you see a large stone structure with the top lit up, illuminating a whale skeleton in the distance. Swim to the top of this pillar to find the next Shell (10/19).
Now dive off the edge to see another Hidden Pool (14/20) at the tail end of another skeleton.
Ahead you may notice some glowing wires near a metal door. Swim towards the closest wire and follow it to the right into a cave, avoiding the mines if you can. At the end of the wire will be a generator that you can interact with.
Now head out of the cave where you came from and follow the second wire to the right. It will go into a cave, but you should see a Hidden Pool (15/20) tucked into the right side of the path.
Follow the wire into the cave and activate the generator, which will open the door so you can progress. Follow the cave and interact with the shark when you come to it so you can proceed.
In the following cave there will be a Shell (11/19) hidden away towards the ceiling as the cave begins to turn right.
When the cave ends, follow the pillars down. As you get close to the bottom of the closest pillars, you should be able to see an illuminated Shell (12/19) at the edge of the cliff.
Continue diving past the cliff edge and you should see a Meditation Statue (10/12) on some rocks at the sea floor.
Now there will be an enormous hole in the wall ahead of the statue, swim to the top of it and you will see a large rock protruding above. On this rock will be a Hidden Pool (16/20).
Now swim down through the hole under you, head into the glowing pool and complete the hub area. During the cutscene, you will see yellow Giant Squid emerge (if you had a keen eye, you may have noticed in the previous area as well, swimming in the darkness). Swim up to the body of one and hold to ride it, unlocking an achievement:
Discover those that lurk in the abyss.
Now swim through the doorway and follow the linear path until you come to the large triangular structure. You need to swim through the minefield and enter the structure through the orange center to complete the chapter.
This next chapter is very linear, so just keep following the path while avoiding the mines embedded in the walls. Eventually you will come to a button you can interact with. Continue down the path that opens up and you will come to a large minefield. You need to head to the other side and exit the orange triangular hole in the opposite wall. I recommend swimming towards the bottom as it seems to be less populated with mines. When you reach the next room, there will be a cutscene.
When you regain control, swim through the hole and head towards the shark. After the cutscene, continue down the path. When you come to a room, swim to the opposite wall you will be able to climb up it and walk on the surface. Run () up the stairs and interact with the fountain to open the door. Dive into the water and you will see a building with a large staircase. Swim around the left side of this and you will see a Hidden Pool (17/20) on the opposite side.
Nearby, atop a stone structure will be the next Meditation Statue (11/12)
Face the same direction as the statue, and you should spot a Hidden Pool (18/20) in the distance.
There will be a pillar immediately near the pool (along with a skeleton). Swim up to the top of this pillar to find a broken walkway. Climb up onto this walkway and run through the waterfall to find a hidden pool. Jump into this pool and swim to the back to find a Shell (13/19) at the end.
Now backtrack out of the pool, run back through the waterfall and dive into the water. Swim past the stone structure ahead of you and swim to the left corner of the next nearby structure where you will be able to climb up.
Climb the staircase on this structure to find the next Shell (14/19)
With the collectables out of the way, dive off the right side and follow the chain to find a crank to interact with.
Follow the second chain to a crank that will be locked behind a door. Swim around to the back of the building and swim to the surface, and you will be able to climb up and interact with a fountain. Dive back into the water and turn the crank to open the door and proceed with the story.
You will see a large fountain in the next room. Follow the liquid path to small fountain, and interact with it so you can swim through the ceiling. When you reach the surface, climb out and dive off of the broken bridge into the water below.
As you hit the water, look towards your character's left and you should be able to spot a Hidden Pool (19/20) in the sand
Now interact with the fountain at the end of the small aqueduct.
Follow the liquid to the other side and you can follow the empty aqueduct to the second fountain, but on the way you should see the last Hidden Pool (20/20) in the sand on the right.
This will unlock an achievement upon interaction:
Release fish from all the hidden pools.
If you swim up the nearby ledge and look to the left, you should also see the last Meditation Statue (12/12)
As with the pools, this final statue will also unlock an achievement:
Swim to the end of the aqueduct and interact with the fountain there to open the door. Instead of going through the newly opened door, turn towards the wall of seaweed and swim through it.
When you're past the seaweed, follow the wall to the right and it will curve around to a wall, swim up to the surface and climb up onto the platform to find a Shell (15/19) in the middle of a gazebo.
Now follow the liquid to the new room, where you will find another fountain to interact with. Swim up to the surface and climb out, then interact with the fountain to open the door. Follow the linear path around the building and dive off the broken bridge into the water below for another sea current section. If you don't have the Jetstream achievement yet, the schools of fish here are brown.
At the end of the current section, you will see two chains leading to two cranks at the top of the room. Interact with both cranks and swim through the whirlpool at the bottom to enter the hub area. Swim to the orb in the center of the hub and interact with it to continue to the next area.
As soon as you have control, swim to the surface and turn to the right to find a Shell (16/19). You simply need to swim under it to pick it up.
You've probably noticed the shark swimming around you. Swim up to it and ride it with for your next achievement:
Now swim ahead until you notice the mines connected to a larger structure with wires (note that you can dash while riding the shark using ). Swim into all of the mines to destroy them and raise the water level. The camera will point you where to go after the water level rises, so swim up there for a short current section and another set of mines to destroy.
You will repeat this process 3 more times, the final time leading you to a large open area with giant whales and the large triangular structure in the distance. First, you want to look to the right immediately after gaining control of your character. There will be a small platform with a Shell (17/19) that you will need to jump nearby to grab. Gather momentum and swim leap through the surface while mashing and you should grab the shell sooner or later.
Now follow the wall in the opposite direction, and as you pass by the entrance of this area, you will notice a small island in the distance with penguins and a polar bear on it. Swim there and climb up onto the surface to unlock an achievement:
There is also a Shell (18/19) near the bear.
Now swim to the central area with the Blue Whales. Swim near one's eye and hold to ride it, and simply wait while holding on and eventually it will leap from the water, granting you an achievement:
Breach the water on the back of a blue whale.
Now you're free to swim into the orange triangle in the center of the Triangular structure. You will appear in another minefield, but you can destroy the mines now, so speed through the area for a cutscene.
At the end of the cutscene will be the end credits, that will unlock you an achievement:
During the credits, you will be able to swim around. Stick to the right side of the screen and eventually the final Shell (19/19), unlocking the final achievement:
Add all secret shells to your collection.
